From memory, may contain some errors:

var doc = XDocument.Load(...);
var groups = doc.Descendants(ProductGroup);

var newDoc = new XElement("ProductGroups", 
    groups.Select(pg => new XElement("Name", 
            new XAttribute("Id", pg.Element("Id").Value), 
            pg.Element("Name").Value) ));


newDoc.Save(...);
